Working With Rails

Depends on what you needed done.

Do you need to parse a RSS feed?

Or do you want to generate your own RSS feed?

->how to install rss gems and from where ?(if it is needed )

I need to generate my own RSS feed

Have you tried the tutorial here ?

i tried but can’t could you please explain in detail
with sample app

This tutorial is old and outdated – you should use a modern REST approach.

What you need is basically:
- auto_discovery_link_tag in your head section. Use formatted_whatever_url as the link. For example, if you have a post resource, this would be formatted_posts_url(:rss) (or even better :atom).
- In your PostsController#index, use a respond_to block and add format.rss (or format.atom).
- Create a corresponding template (app/views/posts/index.rss.builder or index.atom.builder) and create the basic xml structure in it that an RSS feed needs.
- If you use Atom instead of RSS, you can also use the AtomFeedHelper that ships with Rails.

where to add format.rss (or format.atom).

You add it in your controller code, inside the action which would render the feed.

in controllers i added ‘feed’ and ‘rss’ as actions
this format.rss means wat i should code
and thank you for your replay

You don’t need to add a feed or rss actions in your controller. You can just add it to your index action. Lets assume you have a Post model and PostsController as an example.

class PostsController < ApplicationController

def index
@posts = Post.find(:all)
respond_to do |format|
format.atom
end
end

end
_

Create an app/views/posts/index.atom.builder file which contains the following:

atom_feed do |feed|
feed.title(“My Atom Feed”)
feed.updated((@posts.first.created_at))

for post in @posts
feed.entry(post) do |entry|
entry.title(post.title)
entry.content(post.body, :type => ‘html’)

entry.author do |author|
author.name(“EMF”)
end
end
end
